U.S. sales of E15 gasoline reached a record 1.52 billion gallons in 2025, up 23 percent from the previous year. According to the Renewable Fuels Association, growth was driven by more stations offering E15 and higher per-station sales. Iowa led the surge, with sales jumping 60 percent to more than 410 million gallons. Minnesota drivers bought an estimated 169 million gallons, bringing the two-state total to 579 million gallons. Nationwide, about 4,600 stations offered E15 by the end of 2025.
Lower prices, often 25 cents per gallon cheaper than regular gasoline, and federal infrastructure funding also boosted demand. However, regulatory uncertainty remains a barrier. Temporary summer waivers allow E15 sales, but a lack of permanent approval has slowed broader adoption. Industry groups continue to push for federal legislation enabling year-round nationwide sales. A September 2025 study showed full adoption of E15 would add $25.8 billion to U.S. GDP.
